Description

Technical Field

[0001] This utility model relates to the field of pipeline equipment technology, specifically an energy-saving insulated pipeline elbow device. Background Technology

[0002] Elbows are a common type of pipe fitting used in plumbing installations. They are used to connect pipes at bends and change the direction of the pipes. Other names include: 90-degree elbow, right-angle bend, elbow, stamped elbow, pressed elbow, machine-made elbow, welded elbow, etc. The purpose of pipe bends is to connect two pipes with the same or different nominal diameters, allowing the pipeline to make a certain angle turn.

[0003] Traditional insulated elbows generally have unsatisfactory insulation performance, and the insulation materials used have poor weather resistance. When exposed to the outdoor environment for a long time, they are prone to aging and cracking due to ultraviolet radiation, temperature changes, and humidity, which reduces their insulation performance. Therefore, those skilled in the art have provided an energy-saving insulated pipe elbow device to solve the problems mentioned in the background art. Utility Model Content

[0013] As a further improvement of this utility model: the inner insulation layer is made of polyurethane foam material wrapped with an aluminized polyester film, and the protective layer is made of high-density polyethylene material.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This energy-saving insulated pipe elbow device significantly improves insulation performance and structural strength through a multi-layered structural design consisting of a protective layer, an outer insulation layer, a reinforcing layer, and an inner insulation layer. The high-density polyethylene protective layer resists external corrosion, while the rubber strip outer insulation layer and the inner insulation layer, which consists of polyurethane foam wrapped in an aluminized polyester film, work together to enhance the heat insulation effect.

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1-5 In this embodiment of the utility model, an energy-saving insulated pipe elbow device includes an elbow body 1, which includes a protective layer 101, an outer insulation layer 102, a reinforcing layer 103, and an inner insulation layer 104. A slot 2 is provided at one end of the elbow body 1, and a clamping plate 3 is fixedly connected to one end of the elbow body 1. A sealing gasket 4 is fixedly connected to the upper surface of the clamping plate 3. The device combines energy saving, durability, and convenient maintenance, thereby greatly increasing the practicality of the equipment.

[0025] The slot 2 is compatible with the card plate 3. Two mounting plates 5 are fixedly connected to the outer surface of the elbow body 1. Each mounting plate 5 has a ring-shaped arrangement of connecting holes 6 on its outer surface. Each connecting hole 6 has a connecting bolt 7 inside, which facilitates the installation of the equipment. A triangular plate 10 is fixedly connected to the outer surface of the elbow body 1. Two ear plates 8 are fixedly connected to the outer surface of the elbow body 1. A ring-shaped arrangement of reinforcing plates 9 is fixedly connected to the outer surface of each ear plate 8. The side of each set of reinforcing plates 9 that is close to each other is connected to the elbow body 1, which greatly increases the overall strength of the elbow body 1.

[0026] The inner wall of the protective layer 101 is connected to the outer insulation layer 102, the inner wall of the outer insulation layer 102 is connected to the reinforcing layer 103, and the inner wall of the reinforcing layer 103 is connected to the inner insulation layer 104. The reinforcing layer 103 is made of glass fiber reinforced plastic, the outer insulation layer 102 is a rubber strip, the inner insulation layer 104 is made of polyurethane foam material wrapped in aluminized polyester film, and the protective layer 101 is made of high-density polyethylene material. This allows the elbow body 1 to have the characteristics of resisting external erosion, enhancing heat insulation effect and improving overall pressure resistance, thereby making the elbow body 1 perform better.

[0027] The working principle of this utility model is as follows: First, the elbow body 1 can be connected to the insulated pipe using the slot 2 and the plate 3. The sealing gasket 4 can prevent leakage at the pipe connection. The ear plate 8, the reinforcing plate 9 and the triangular plate 10 can prevent the elbow body 1 from deforming. The innermost inner insulation layer 104 is made of polyurethane foam wrapped with an aluminized polyester film, which can reduce heat conduction by more than 90%. The middle reinforcing layer 103 is made of glass fiber reinforced plastic, which greatly improves the overall pressure resistance. The rubber strip of the outer insulation layer 102 further blocks 30% of heat loss. The outer high-density polyethylene protective layer 101 can resist the damage to the elbow body 1 caused by the high temperature outside.
